Batteries store electricity and can be charged and used as a power source when placed in a Battery Array. Energy stored in a battery is measured in kJ (kilo-joules). A kiloWatt-hour is equivalent to 3600 kJ, or 3 cheese burgers.

The Alkaline Battery can store 4000 kJ of energy. For reference, a lump of coal contains 50 MJ of energy (50 000 kJ) and a cheese burger contains 1250 kJ of calorie energy.

Recipe

The Alkaline Battery is crafted from plastic ingots, an iron ingot, gunpowder, and a zinc ingot.

Uses

Batteries can be placed in a Battery Array, which will automatically recharge a battery with excess electricity and drain the batteries when the demand for electricity exceeds the supply from generators.
